BUTTER MAKING AND MOLDING MACHINE.

Specification of Letters Patent.

Patented Jan. 9, 1917.

Application filed March 23, 1912. Serial No. 685,823.

To all whom it may concern Be it known that I, OHARLns VOLKMANN, a citizen of the United States, residing in the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Butter Making and Molding Machines, of which the following is a specification.

My invention relates to that class of machines which are designed to churn and work the butter and mold it into bricks of a predetermined size and has for its object to provide a machine which will perform the complete operation without the necessity of the operator touching the loutter with his hands at any period of its manufacture,

and has for its further object to provide an improved device for Working the butter and has for its further object to provide a more positive feed than those which are employed in devices of this character and has for its further object to provide a new and improved faucet for draining the buttermilk and salty water off when the butter has been churned and washed.

My means of accomplishing the foregoing may be more readily understood by having reference to the accompanying drawings, which are hereunto annexed and are apart of this specification, in which:

Figure l is a side elevation partlyin section to show the interior construction. Fig. 2 is an end view with the housing removed. Fig. 3 is a view taken on the line 02-m in Fig. 1, in the direction indicated by the arrows. Fig. 4 is an end view of the molding device. Figs. 5 and 6 are enlarged detail views, showing the means for guiding the molding device.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawings, my device consists of a vertical rectangular portion 1 and a horizontal cylindrical portion 2. In the vertical portion I mount dashers 3 and 4:, which are carried by shafts 5 and 6. These shafts are hinged at 7 and secured to the other end 8 of the shaft by means of a meshes with thegear 13, which is driven bv the gear 14 mounted upon a shaft 17. These gears are mounted in a housing 15 and are completely inclosed so as to be inaccessible to dirt or water and are designed to be run in oil, so that they will be thoroughly lubricated under all circumstances and in this manner greatly minimize the wear and noise.

In the cylindrical portion 2 is mounted a conveyer screw 16, which is secured to the shaft 17 which also carries the gear 14 above referred to. This shaft 17 extends outwardly through the housing 15 and may be driven by any suitable power (not shown).

19 is a screw which is fitted to and coincides with the groove in the conveyer 16 for the purpose of making a positive feed, it being driven by the frictional contact with the conveyer 16.

20 and 21 are corrugated rolls, which are designed to assist in the operation of working the butter. The roll 21 is carried by a shaft which extends through the wall of the vertical portion of the machine and has secured to its end a lever 22, which is provided with a handle 23, which has mounted thereon a clutch 24, which is adapted to engage notches 25 cutupon the segment 26, which is secured to the side wall of the machine.

It will be apparent that by moving this lever either up or down the distance between the two rolls 20 and 21 will be correspondingly varied and the butter will be worked to a more or less degree.

While the butter is being churned and worked I fit a cap 27 indicated by the dotted lines inFig. 1 to the cylindrical portion. The conveyer screw is then rotated in a re verse direction. This causes the cream to be passed upwardly and it is brought in continued contact with the dashers 3 and 4.

gated rolls and 21, which will thus Y the cap 27 is removed and the WVhen the butter has come, a faucet 28 is opened, the buttermilk drained from the in terior and the salty water is put in. The rotation'of the conveyer screw is then continued and the butter is thoroughly washed and worked, it being apparent that the conveyer screws 16 and 19 will cause it to betherein, is mounted the upper portion of the molding device, which is designed to print any desired configuration on the face of the brick of butter. This is constructed, as better seen in Figsa5 and 6, with two wedges 35 and 36, which are attached to upwardly extending lugs 37 and 38 by means of bolts 39 and 40. r f

It will be apparentfrom an inspection of the drawings, that these wedges can be so arranged as to contact with the sides of the vertical blades 31, this preventin'g any butter from assing up and beyond the print- 11151 portion of the mold.

The side walls 41 of the casing which inclose the molding mechanism are provided with slots 42 and 43, to which are fitted rollers 44, carried by shafts 45 journaled in an upwardly extending portion 36 of the stamping member 47. This slot is provided with inclined portions 48 and 49, the use of which will be hereinafter explained.

If the printing member was swung entirely from the roller 44, it will be apparent from the description that there would be.

nothing to prevent its turning entirely over when it was passing over the'wheels .33and mold the sametimelthis constructionf '34. I prevent this by'means of a guide 50, which is secured to the shaft 45 and is adapted to ride the slot 42. Pins '51 and 52 are mounted in said guide which will contact withthe upper surface of the stamp 47,

thus preventing its movement beyond a pre-,v

determined po nt. Y

meansof-whichjthe height of the device may be varied and consequently the size of'the 7 slot, at this period the pressure of n Will. us t osm e' ep ardlv and inxc'rd r 53, thus preventing the free movement of the molds, and in this manner avoiding any possibility of the forming of a brick of under size due to the mold moving before the butter has completely filled the space provided or it. a

The shaft 57 of the'wheel 34 is mounted in a 'box58, which is provided with both vertical and longitudinal adjustmentfor the purpose of varying the height inthe same manner as the shaft 53 has been varied, while the screw 59 is provided to enable the operator to tighten the chain.

The'ends 60 of the casing 41, which inclose the molding mechanism, are provided with outwardly extending lugs 61, which have a slot therein through which passes a bolt 62, which is secured 'to the wall of the casing41. When the machine has finished its operations, by removing thisscrew, it becomes possible to lift the upper half of the cover off of the molding mechanism so as to wash the interior without any 'ditliculty. A

lug 61 has an outwardly extending portion 7 63 in which is mounted a bolt 64, which'igprovided for the elevation of the wall 65of the casing, so as to keep the distance from its inner edge tothe wheel 33, as otherwise,

erates to smooth the lower surface of the butter so that when it passes off of the said base 68, it is a perfect brick which is ejected upon a suitable inclined plane 69, which carries it to the operator. It will be apparent that as long as there is butter in the cylindrical portion 2 of the machine it will continue this operation of automatically molding the bricks of butter at the same time, inasmuch as the molding mechanism is entirely actuated by the butter itself, that a full and complete brick is insured during each operation, until the supply of butter is eased up, at which time it is possible that there will remain one or two bricks in the molding part of the machine. These can be delivered by the operator rotating the handle 66, which will bring them past the spring-pressed base 68 to a position to which they can be de livered out of the mold.

The action of gravity in ejecting the but ter from the walls is not always suflicient as the butter under different temperatures will act difi'erently, and on the surface both of the stamping members 47 and the sides of the vertical blades 31 to overcome this difiiculty and in order to prevent the brick being passed on around the machine, I provide the inclined plane 49, which operates to carry the stamping member 47 downwardly and has the effect of positively ejecting the butter from the mold, so that its mechanical delivery is assured under all conditions.
